CLOSURE 1 Application filed Januar eo, 1932. Serial No. 589,809.

' This invention relates to closures, especially closures for windows of buildings, and particularly closures consisting largely of a sheet or sheets of pervious material supported by a skeleton frame. v 1

A principal object of this invention is the provision of a closure of the type specified which will form a complete closure of an open window so that there will be no opportunity at'anypoint for insects of any considerable size to enter.

A further object of the invention is'the provisionof a closureof the typespecified, which includes a plurality of parts, prefer- 3 ably two, in which the outer-sliding section is longer than the inner sectionor'sections,

and extends both above and below the inner section or sections.

()ther objects and advantages will appear as the description of a particular physi embodiment selected to illustrate the invention progresses, and the novel features of the invention will be particularly pointed out in the appended claims.

In describing the invention in detail, and

the particular physical embodiment selected to illustrate the invention, reference will be had to the accompanying drawing and the several views thereon, in which l1ke characters of reference designate corresponding parts throughout the several views, and in which: I

Figure 1 is an'elevational viewof awindow and frame, viewed from the inside,'showi-ng my improved'closurein place therein; Fig. 2

is a sectional view on the plane-indicated by the line II II of Fig; 1, viewed inthe direction of the arrows at'the ends of the line; Fig.3 is a sectional view on the plane indicated by the line II-I-III' of F ig. 1, viewed in thedirection of the arrows at the ends of the line; Fig. 4 is a sectional view on the plane indicated by the line IVIV of F1g.

, 1, viewed in the direction of the arrows at the ends of the line; Fig. 5 is an elev face view of my improved closure.

My closure consists generally of a part A and a part B. Each of these parts may be considered as a substantially rectangular frame supp a PerviouS material as 1 der 20; the bottom rail 7 bearing against the and 2, suchas ordinary and well known wire screening. Each rectangle or frame as A and B, iscomposed of what are in effect top and'bottom rails, and side rails. Section A,

has the bottom rail 3, the top rail 4, the

right side rail or stile 5 and the left side rail orstile 6. The section B has the bottom rail 7 the top rail 8, the right side rail 9, and the. left side rail 10.

The two frames A and B are attached together by dovetail keys as 11 and 12. V This construction, involving the dovetail keys 11 and 12 is merely representative of ordinary and well known constructions and is not intended to be exclusive. By this construction there is the possibility of sliding between the frames A and B so that they may be moved or slid one upon the other so as to extend a distance substantially equal to twice the length of one or be positioned so as to be practically the length of one or any length intermediate these extremes.

A top rail 8 of section B rises above the top rail 40f section A, as best shown in Fig. 2.

The bottom rail 7 of the section B extends below the bottom rail 3 of section A, also best shown in Fig. 2. By such construction the bottom rail 7 always contacts the sill 13 of a window in which the closure isplaced and the bottom rail 3 is always free from the sill 13.

At the same time, the top rail 8 of section B contacts the bottom rail 14 of the sliding sash and the'top rail4 is always free from the bottom rail 14 ofthe sash.

' As best shown in Fig. 3, the rail 9'of'secti0n I B fits closely against the front stop 16 o'f'a window frame. This is best accomplished by enlarging the stile or side stop 9 sothat the face IZthereof is on a line withthefa'ce 18 of the side rail or stile 6 of frameA and the bottom edge'is on a line with the bottom ofthe edge of rail 3. Bysuch construction the closure bears tightly against the front stops 16 and 19.

As best shown in Fig. 2 the bottom rail3 of the section-A bears tightly against the shoulder 20 of the sill 13, so that by means of the bottom rail 3 bearing against the shoulsill 13; the end rail or stile 6 bearing against the front stop 19; and the end rail or stile 9 bearing against the front stop 16, there is no space for insects to enter along the bottom and bothsides of the closure.

Along the top of the screen or closure, the entrance of insects is prevented along the top rail 8 of section B by reason of the contact between the lower rail 14- of the sash and the rail 8. Along the remainder of the top of the closure I have provided a shoulder 15, best shown in Fig. 2. This shoulder 15 may be attached by any well known means, as by screws 24 to rail 4. It, of course, is understood that integral construction is not excluded. It has a surface 21 which contacts the inside surface 22 of the lower rail 1 1 of the sash. This shoulder 15 has a cutaway portion-at 23 to allow'for the front stop 19.

From the hereinbefore given description, it will be seen that applicant has provided a closure which is prevented from moving inward- 1y by contact of its side rails or stiles with the front stops of a window frame and by the shoulder of the sill contacting with one bottom rail. The closure is prevented from moving outwardly by a shoulder as 15 which functions also in addition to close an otherwise open space by which insects or other undesired things might enter a window.

By the construction of closure as hereinbefore set forth, applicant has provided a closurewhich is free from rattle because the closure is practically wedged between the lower rail of the sash, as 1st, and the frame. The top end of the closure cannot move outwardly because of shoulder 15 and it cannot move inwardly because of the contact between stile 6 and front stop 19. Section B cannot move outwardly because of its contact with the lower rail 14 of the sash.

At the lower end of the closure, the lower rail 3 of section A hearing against the shoulder of the sill 13 prevents the closure from moving inwardly and the downward pressure of the lower rail 14 of the sash forces the innor corner of the lower rail 7 of section B so firmly against the sill 13 that no outward movement may takeplace. 1

Heretofore closures somewhat like the present closure have been suggested but they have required two shoulders corresponding to shoulder 15, that is, one shoulder on section Band another shoulder on section A. By the improved construction, as hereinbefore set forth, by which section B bears the entire weight of the, sash and contacts the sash along its entire length at the top and contacts the sill 13 along the entire length of the section at the bottom a single shoulder only as 15 is necessary, thus avoiding a part rather difficult to manufacture, because where two shoulders are used one on one section and one on the other section, they must be so nested that they both bear against the front face 22 of the lower rail 14 of the sash. This makes a construction rather more expensive than that illustrated and described in this application. v

Although I have particularly described one particular physical embodiment of my invention'and explained the principle, and mode of operation, and construction thereof, nevertheless, I desire to have it understood that the form selected is merely illustrative but does not exhaust the possible physical embodiments of the idea of means underly ing my invention. 7

What I claim as new and desire to secure by Letters Patent of the United States, is: 1: In a closure, incombination: two

frames, each including a top, a bottom and two side rails, the bottom rail of one frame being slightly below the bottom rail of the other frame, and the top rail of the one frame being slightly above the top rail of .the other frame, whereby the one frame will alone contact the sill of'a window and the lower rail of a sash; the other frame including'a shoulder formed to contact the inside face of the lower rail of a sash and formed with a cut away portion for the reception of the front'stop of a window; the inside faces of the outside side rails of each frame being in line. i

2. In a closure, in combination: two

frames, each including a top, a bottom, and

two siderails, thebottom rail of one frame being-slightly below the bottom rail of the other frame and the top rail of the one frame being slightly above the top rail of the other frame,v whereby the one frame will alone contact the sill of a windowand the lower rail of a sash; the other frame contacting the shoulder. of the sill and including a shoulder formed to contact the inside face of the lower rail of a sash and formed with a cut-away portion for the reception of the front stop of a-window; the inside faces of the outsideside rails of each frame being in line, whereby the window opening is positively closed along all four sides.
